AI Max for Search is a set of Google's AI features that sits on top of your existing Search campaigns. It widens the searches your ads can match, rewrites ad text for each query, and can send people to a better landing page. In September 2026, Google automatically upgraded campaigns using automatically created assets or campaign-level broad match to AI Max. Dynamic Search Ads follow in February 2027.
What Is AI Max for Search? A Plain-English Google Ads Tutorial Think of AI Max as a smart assistant that Google bolts onto a normal Search campaign. Your campaign, budget and bidding stay where they are. What changes is how much freedom Google has to decide which searches trigger your ad, what the ad says, and where the click lands.
AI Max for Search reached general availability in April 2026, after a beta period in which advertisers could switch it on voluntarily. The September change is the moment Google stopped waiting for volunteers. Google's own direction is clear: Search is becoming a machine-assisted channel, and Google automation is the default way to run it.
